4 SHEETS-SHEET 4- to the'cross bar 21 extend upwardly therefrom on opposite sides of the rear frame bar -'lfand carry an anti-friction roller 23 throw.

Whichre'stsupon the rear framebar. A lever is journaled to swing upon a vertical axis in a lbracket 24 (see Fig. 1) on `one side of the frame opposite the rear end of the pole. This lever is provided with an upper forwardly extending ;arm; 25; and a lower rearwardly extending arm 26. The

of the pole by a link 27 and the lower arm is connected tothe seat bar at a point intermediatethe ends of the latter bylinks28.

A series of holes are preferably providedin the arms25and 26 so that the connections i betweenthese' arms and the links 27 and 28 can be adjusted, as desired, to vary the When the operator shifts the seat to one side, the connections between the seat bar and the pole will shift the rear end of the latter and the forward end of the frame in the opposite direction, so that the frame will be angled relatively to the pole and will be guided or steered laterally. The rear en d of the pole is connected by a vertical pivot bolt 29 to the upper portion of a front arch 30, the lower end of the bolt being provided' with an eye 31 (see Fig. 5) through which the upper portion of the front arch bar 30 extends. A cast piece 31 ts over the upper portion of the eye 31 .and engages the arch bar and clamps these parts together when the nut on the upper end of the bolt '29 is tightened. The cultivator beams'32 carrying the shovels 33l are mounted upon the lower, horizontal end portions of the front arch. In the form shown, sleeves 34 are journaled upon the lower horizontal end portions of the front arch and coupling brackets 35 are adjustably clamped thereon. Verticall-y adjustable spindles 36 are clamped to the couplings 35 and yokes 37 on the forward ends of the beams 32 en- The cultivatprbeams arefreeto swing upon the ends ofthe front-arch to and from working po-Y the sides of the beams.

sitionbut are normally held against lateral swinging movement by links38 (see Figs. 1 and 4) which extend between lugs 39 on the coupling brackets 35 and clips 40 secured to These connections hold the cultivator gangs against lateral swinging movement about the vertical spindles 36,but preferably, the links 38 are adjustably connected to the clips 40, so that theV position of the cultivator beams can be adjusted. A

. The cultivator beams 32 are provided with stirrups 41 for the riders feet, so that he may shift the rear end of the seat bar by pushing) upon one or the other of the cultivator cams. As the rear end of the tongue vor -pole is shifted in one or the other direction, the front arch which is connected thereto by the bolt 29, is also other. To brace the ends of the laterally shifting front arch, a pair of links 42 are pivotally connected at their lower forward ends to brackets -43 (see Figs. 2 and 4), fixed to the lower end portions of the arch adjacent the inner ends of the sleeves 34. The upper rear ends of these links pivotally engage suitable brackets 44 (see Figs. 1 and 3) secured to the rear end portions ofthe cultivator frame. These swinging links diverge outwardly and rearwardly from the ends of the front arch so that the gangs are maintained in a position parallel to the line of draft as the rear end of the pole and the front arch is shifted to one side or the other.

Clips 45 are clamped upon the outer ends of the lower horizontal spindles of the front arch, and a pair of angle pieces 46 are secured thereto. Additional brace links 47 are'pivotally connected at their lower ends lto the angle pieces 46 and at their upper ends to a pair of arms 48 which extend for wardly from brackets 49 on the outer or supplemental frame bars 7. The two sets of swinging links 42 and 47 securely brace the ends of the swinging front arch which carry the gangs. The angle pieces 46 are connected by chains50 to the lower ends of a pair of draft bars 51. The upper ends of these draft'bars engage a whiie-tree 52 which is pivotally connected to the pole 9. Swingle-trees 53 are connected to the draft arms 51.

The cross shaft 15 is journaled at its ends in the brackets 49 andis also journaled in brackets 54 fixed to the main side bars 5. The ends of the shaft are provided with depending arms 55 which are connected by links 56 to the lower ends of the depending wheel sections 2 of the arched axle. These arms are also connected by lift springs 57 to a pair .of clips 58 fixed to the rear ends of the outer supplemental side bars 7. The bracket 49 on one side of the machine is provided with a notched segment 59 and a lever 60 fixed to the adjacent end of the shaft 15 is provided with a dog 61 arranged to engage the notched segment and hold the shaft 15 in adjusted position. Between the pairs of brackets 49 and 54, the shaft 15 is provided with sleeves 62 having upwardly and rearwardly projecting arms 63 extending therefrom. These arms are connected by depending chains 64 to the cultivator beams 32. By shifting the lever 60 in opposite directions, the cultivator beams are raised and lowered and the wheel sections of the arched sections are swung forwardly and back to balance the cultivator when the gangs are raised. By this arrangement, the forward draft of the team levers 70 can be actuated to independently meinen' aids in` lifting the cultivator gangs Vfrom working position. The eultivatorbeains'are also connected by a chain 65 to a pair of arms 66.` These arms are 'mounted upon hubs 67 (see Figs. land-8) and these hubs are carried on spindles 68 which extend through the clips 58 and through notched segments 69 fixed to the rear ends ofthe main frame bars 5. Levers 70 xed to the hub 67 are provided with dogs 71 arranged to engage the segments 69v and .fhold the levers in adjusted position. These depth regulating levers 70 are independent of the main raising and lowering lever 60, but inasmuch as the levers are .connected to the gangs by flexible chain connections, the

lever 60 can be properly operated to raisev and lower the same simultaneouslyand the adjust the working depth thereof, Ithe operation of the depth regulating levers being and lowering lever. Furthermore the lexi ble chains uphold the rear ends 'of the gangs but do not interfere with the .lateral shift thereof when the pole and frame are angled by the seat bar.

It should be noted that the swinging bracev links 4:2 and 47 extend between the ffront arch and the main frame, so that the depending sections of the wheel axle are free to swing with the main raising and lowering shift lever to balance the ciiltivator 'when the gangs are raised and so that the draft of the team may be utilized in raising the gangs.

-By pivoting the seat bar at a point-near the front of the machine, the lateral swing of the seat at its rear end, necessary to guide the cultivator, is,approximately'in a straight transverse direction and ythe riders body is not twisted when the seat is moved. By forming the seat bar of separate members spaced apart, the rider has a full view of the row of plants over which thecultivator travels,'and'he can readily guide the gangs in proper.relation to the plantsby swinging the seat to oneside or the other and pushing the gangs inthe opposite direction. At the same time, his hands are free to guide the team.
